Suppose i have got the following java files
1.java, 2.java and 3.java
3.java is the main file which include classes 1.class and 2.class
So i compile 1.java and 2.java first before I compile 3.java

Now all these r in a directory say "a/b/c"

is it right to give inside the files 1,2,3.java
package a.b.c;

and then the rest of the program
